To (ll/I whom it may concern:

Be it known that I. ZnLIUs B. W A NTQ a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Therapeutic Lamps, of which the folowing is a specification.

My invention relates to improvements in the class of therapeutic lamps in which the illuminating mediumas an incandescent electric lamp-is combined witha reflector arranged to direct the light-rays, for their therapeutic effect, against parts of the body of a patient undertreatment.

The primary object Of my invention is to provide a multiple lamp in the class referred to, of novel construction adapting it to afford the advantages hereinafter stated; and a further object is to provide simple and novel means for supporting the lamp by suspension, whereby it shall be adapted to be readily adjusted to any desired angle for directing the light-rays.

In the accompanying drawings, Figure 1 shows my improved therapeutic lamp by a view in sideele-vation; Fig. 2 is a top plan view of the same; Fig. 3, a bottom plan view of a disk-shaped coupling-head upon which to make electrical connections of the lamps with the conductor-wire for'supplying current thereto; Fig. 4, a section taken at the line 4 on Fig. 2 and viewed in the direction of the arrow, and Fig. 5, a section taken at the line 5 on Fig. 2 viewed in the direction of the arrow and enlarged. v

The base 6 is a metal plate 7, preferably of disk-shape and having a highly polished under surface to adapt it to reflect light-rays, with a post 8 rising from its center, about YfllCll are formed hood-seating Openings, 9, 10, 1]., l2; and a metal flange 13 extending circumferentially about the plate and preferably'fiaririgbiit'wardlyfrom its edge, the inner surface Of the flange being also highly polished to adapt it to reflect light-rays.

In the Openings 9 to 12, inclusive, are seated at their wider beadedends, respectively, hoods 14, 15

1 all b ing gi l kfiflmfiructione rants sitters-un *generai' cone frustum shape with its apex removed and having formed about its apical end a perforated heat- .ventilating collar 18, on which is mounted a socket 19 for an incandescent electric lamp 20 inserted into it from within the hood, which surrounds it, the socket having connected with it a conducting-wire 21 termiin a plugv 22 of insulating material containing metal-lined sockets 23, 24. The inner surfaces of the hoods arehighly polished to cause them to reflect the light from their contained lamps through the Openings in which they are seated, and which dispose the four hoodsin pairs at right-angles to each other. Three of thehoods are shown to be permanentlyfastened on the base 6,-by suitable clips 25 engaging their beaded edges,

three of these clips so fastening each hood, except the hood 17, which is fastened by only two clips 25, and .by a slotted finger 26 releasahly engaging the beaded hoodbase, being secured in place by a set-screw 27 passing through its slot into the plate 7. By loosening the setscrew and withdrawing the finger from engagement with the respective hood-base, the hood 17 is released and may be withdrawn from the clips 25 overlapping its beaded edge, to enable this hood to be used separately,

nipulation of the removable hood itis provided with a handle 28, shown as projecting from the collar 18.

The post 8, which is tubular, is fastened rigidly-i1: place by a rod 29 passing through an opening in the center of the plate v7 and having a head 30 on its lower end at which it engages the plate about the opening;

through a-(lisk-head 31 of insulating material, as hard outer conducting-Wire 33, forming an electric connector, is secured, to describe a partial circle, to the under surface of the head 31, by screws 34 at and .between its ends, and an'inner conductor 35, like the conductor 33, is similarly fastened by screws 34 to said head-surface, Pairs of rigid, longitudinally-split coupling-pins 37, 37, fastened by screws, extendupward through the head, the membersof the pairs being thus connected, respectively, with the wires 33 and 35, and each pair is adapted to enter the sockets of a plug 22, which is frictionally held upon them by compressing their split resilient sections. In this way each lamp 20 i may be readily coupled to current-supply wires 38 and I 39, which leadthrough holes 40 in the head, respectively, tO a depending binding-post 41 engaging the connector 33-omthe head 31 and a similar binding-post l 42 engaging the connector'35. The wires 38 and 39 are formed intoa cable 43, provided on its end with a plug (notshown) of the usual kind for insertion into the socket ofan incandescent-electric-lamp fixture; and :it I affords th e" .medium of suspension of my improved therapeutic lamp, from a hook (not shown), which may i be fastened in the ceiling of the room in which the j lamp is used, to adapt the cable to be looped about it. For hiding the mechanism On the under side of the head 31-, an ornamental cup 8 is confined agcainst'it on the post 8.

On the base 6, near the edge, is rigidly fastened an f arm 44 terminating in a circular head 45 with a screwstud 46 projecting centrally and laterally from I Against the head 45 is adjustably confined,Ib'ya thumbl nut 47 engaging the stud, the perforated head 48 of a bent arm 19 terminating at its free end in an eye 50, at which itengages a hook 51 depending from the collar 52 ting the arm 49 to extend at any desired angle from the for thepurpose hereinafter stated. To facilitate mathe rod being threaded at its upper end where it passes rubber, which seats on the post 29 and is fastened by a I nut 32 screwed upon the rod to also fasten the post. An

lamps in pairs at right-angles toeach other permits either pair to be used for covering with the light elongated surfaces. the one hood adapts it for certain purposes requiring only its both.
